This document provides an overview of Rotary membership trends from the 1920s to present day. It discusses how each generation has become less civically engaged over time according to the "Bowling Alone" study. The document also notes that newer generations still want to volunteer but prefer shorter commitments and more flexibility. It emphasizes that clubs must adapt to changing needs by offering mentoring, engagement opportunities, and mixed online/in-person meetings. Survey results show satisfaction is highest when members feel welcomed, encouraged to participate, and that service is effective.
